摘　　要：层面模型即对地层层面的数学描述，是研究地质参数空间分布的重要基础，也是研究三维地层模型的重要方法．层面模型的研究为地质构造图和储层参数分布的绘制和显示提供了方法基础．文中介绍的层面模型方法包括三角面片模型的线性插值法、分片连续加权插值模拟法、双三次Ｂ样条曲面模型计算及克里金层面模型估计，分形层面模型．这几种模型已在微机上实现，取得了较好的显示和绘制效果，并用于油田生产实际．ayer modeling ia a mathematical dicsription of formation layers.it's an important foundation for studying the spatial distribution of geological parameters and an important method of studying three dimentional models.The reseatch of layer models provides methods for drawing and displaying the maps of geological structure and reservoir parameter distribution.The layer simulating methods described in the paper include linear implanting of triangular planer models,successive weighting implanting simulation of separate layers,bicubic curved model calculation of spline B,layer model'estimation by Kriging and fractal of layer models.All the above mentioned models have been realized on the computer.Good results of displaying and drawing have been obtained.They have been applied i production in the oil fields.
